Ignitor testing?

[Lil Red Yarder]

Still trying to get my runner on the road. Finally got to do a fuel system pressure test, compression test. Both were good.

I hooked up my timing light ( probably should have done it at the beginning. The light goes on when it pops. Not when its cranking. Ive checked for spark before and had what looked like good spark.

I check the spark controller. It tests fine.

Is there a way to test the ignitor? My book just says replace it if everything else is good.
